Zinc adhesion on galvanized wire surface and thickness of zinc layer
Factors affecting the corrosion resistance of galvanized wire: The corrosion resistance of galvanized wire is affected by many factors, mainly including the following aspects.
- Smelting technology is good, advanced equipment, advanced process of large stainless steel plant whether in the control of alloy elements, impurities removal, billet cooling temperature control can be guaranteed, so the product quality is stable and reliable, good internal quality, not easy to rust. On the contrary, some small steel equipment is backward, backward process, smelting process, impurities can not be removed, the production of products will inevitably rust.
- Common weight length conversion of barbed rope:
- (2) Spray large number hook mesh guardrail should be used electric spray paint or electrostatic spray paint.
- Large aperture hexagonal net is widely used in mountain, embankment protection, railway and highway isolation barrier, river channel management, soil consolidation berm, water conservancy engineering construction, rivers, DAMS and seawall anti-erosion protection and reservoir river interception, animal husbandry, grassland isolation guardrail, etc.
Crevice corrosion is a kind of corrosion in small area, especially in concealed position, which can form vicious corrosion cycle. Almost all the crevice corrosion can occur in a metal alloy, with gas containing active anionic neutral medium Z is easy to cause crevice corrosion, crevice corrosion often occurs in the aperture of 0.025 to 0.1 mm, because of long time gathered, the cracks will exist a series of impurities, coupled with the external environment of damp easily corrode the area of the gap is small.
Stainless steel barbed rope according to the different categories of nickel applications are not the same, in the dry indoor environment using 304 stainless steel effect is quite good. However, in both rural and urban areas, to maintain its appearance outdoors, it is necessary to stop washing frequently. In heavily polluted industrial areas and coastal areas, the surface will be so dirty that it will rust. But to achieve aesthetic effect in outdoor environment, it is necessary to use nickel stainless steel. Therefore, 304 stainless steel is commonly used for curtain wall, side wall, roof and other building uses, but in the corrosive industrial or Marine atmosphere, it is best to use 316 stainless steel.
- For example, if the barbed rope is used to circle, the cost per meter is only a few yuan, if the ring with other products, it may be more than ten yuan or even 20 yuan, which undoubtedly increases the cost of the user again, so the cattle and sheep with barbed rope is the most economical product
Galvanized hexagonal net is a kind of galvanized metal wire mesh, mesh shape is hexagonal.
Galvanized iron wire will rust, mainly and the thickness of galvanized layer and the use of the environment, galvanized iron wire is also divided into cold galvanized iron wire and hot galvanized iron wire, in general, hot galvanized iron wire galvanized layer is thicker, rust prevention time is longer, generally can be 7 or 8 years without rust. If the galvanized layer is damaged, or long-term use in a humid environment, it will accelerate the rust time of galvanized iron wire.
Post time: 14-04-23- No less than 5 disks should be extracted from each inspection lot for diameter error inspection. 1 point of steel wire should be extracted from each disk to measure steel wire diameter, and the actual diameter of steel wire at this point should be taken as the average value of the two vertical directions. The diameter error of cold-drawn low carbon steel wire should conform to the rules in the table below. The unqualified inspection batches shall be checked one by one, and the qualified batches can be used for engineering.
Some customers just use ordinary fences, but the pictures provided to the barbed rope factory are really used in the barbed rope products of prison, maybe because the customers prefer the style, but such products are really a little overqualified to be installed in ordinary areas. Even if customers prefer such barbed rope products, the high price is also prohibitive. The price and quality of the prison application barbed rope is certainly not the level of the barbed rope we contact in daily life.
1. Used for mountain farming, road isolation, large farming enclosure protection, it is recommended that you choose 3mm wire diameter products.
Heavy duty hexagonal mesh made of steel wire by special machinery woven into a hexagonal mesh net. This kind of mesh can be cut and assembled into fence mesh, mountain hanging mesh, vegetation three-dimensional mesh, composite, etc.
- Galvanized wire A stable layer of zinc is coated on the outside of the wire, which is used to protect the wire and make the wire service life longer. When producing galvanized wire, the wire is pickled. Pickling is to use some acid mist or acid to wash off some oxides on the surface of iron, that is, rust, and some other corrosive substances, to achieve the purpose of cleaning iron, so that zinc will fall off when galvanizing.
- Regular maintenance and maintenance, save a lot of time, but also save the cost of maintenance and maintenance. With good stability, corrosion resistance, greatly prolong the service life. There are many kinds, which can be selected according to different uses. The device for making annealed wire is simple, and the utilization rate of the device is improved.
Post time: 16-06-22- Scope of use: Because the obtained coating is thicker, hot-dip galvanizing has very good protective function than electric galvanizing, so it is an important maintenance coating for iron and steel parts in strict working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, electric power transportation, shipbuilding and other occupations. In agriculture, such as pesticide irrigation, greenhouse and construction industry, such as water and gas transportation, wire casing, scaffolding, Bridges, highway guardrail and other aspects, have been widely used in these years.
Raw material of wire mesh sheet cold drawn low carbon steel wire base material can choose low carbon steel hot rolled disk bar or hot rolled smooth steel bar. The base material number and diameter of cold-drawn low carbon steel wire can be confirmed according to the rules in the table below. During the cold drawing process, the surface shrinkage rate of each drawing should not be greater than the wire mesh before cold drawing. Annealing shall not be carried out during wire drawing. If butt welding is required, the same production unit and base material of the same number should be selected. The appearance quality of wire mesh should not affect wire drawing. When the welding function is poor or brittle fracture occurs, special inspection should be carried out according to relevant standards.
1. Choose according to your dog’s size
Razor wire, also known as razor wire and razor net, is a new type of protective net. Blade barbed rope has beautiful, economical and practical, good resistance effect, convenient construction and other excellent characteristics.
Post time: 29-04-22Large roll galvanized wire welding net is made of high quality galvanized wire welding net, wire through the current, after mutual melting, strong connection point, and the formation of metal mesh. In the use of galvanized iron wire to find the thickness and soft and hard to the size of flowers, weight and softness corresponding to the degree, too soft florets to use fine wire, and heavy flowers, flowers with thick stems to use thick wire.
Specific requirements for the safety of galvanized wire production: clean up all tools and other objects that hinder production in the galvanized wire production environment. Operators in the pickling process, pay attention to the action should be careful, not careless, into the pickling tank must be handled lightly, to prevent splashing on the body. When adding acid, the acid must be slowly poured into the water. It is forbidden to pour the water into the acid, so as to prevent the acid from splashing out and hurting people. Do not hurt yourself or others.
Post time: 10-11-22Now large roll galvanized wire in our life the use of more and more, to galvanized wire products bring a great market, galvanized wire products are more and more types. The surface coating of good quality galvanized wire is continuous and smooth. When the plating parts are installed and combined, there can be no flow hanging, slag or drop remaining, and no surface defects such as iron exposure. Good quality galvanized wire, coating must be uniform, roughly uniform in copper sulfate solution soaking five times without exposing iron. And with hammering test does not bulge, do not fall off. This is a good galvanized wire should have characteristics.
Now hexagonal net is used in a large number of Bridges, piers and bridge buttress inclined plane protection, bridge buttress inclined plane there are many kinds, people according to the inclination of the inclined plane to choose the right hexagonal net, when the inclined plane gentle, people generally use gabion slope protection system, and in the case of steep slope, people will use gabion mesh gravity protection wall.
- Application: Building materials
- Galvanized iron wire is divided into hot galvanized wire and cold galvanized wire, using low carbon steel wire processing, after drawing molding, pickling rust removal, high temperature annealing, hot galvanized, cooling and other processes. It has good toughness and elasticity, and the amount of zinc can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance. Galvanized iron wire can be cut off in the construction of the tie wire, the length of 20cm, 30cm and 40cm, can be cut off according to requirements.
The decorative hook mesh is made of stainless steel, aluminum alloy, brass, red copper and other alloy materials by special technology. It is to do a good decorative screen, today we introduce the aperture and wire diameter of decorative hook mesh.
The quality of hot-dip galvanized barbed wire is only good in the surface of the wire attached to the galvanized layer, and with the chemical reaction, the surface of the zinc layer will gradually lose effect because of the oxidation reaction, this situation is more prominent in the humid area of the environment. And because after all, it is rusty iron wire, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.
